MATCHER.

SPECIFICATION forming part of Letters Patent No. 476,221, dated May 31,1892.

Application fil d November 14, 1889. Serial No. 330,245. (No model.)

To all whom it may concern:

Be it known that I, EDWIN BENJAMIN, of South Evanston, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Matchers, of which the following is a specification.

My improvement relates to matchers which are adapted to work two piecesof lumber at once, and pertains especially to the supporting and drivingmechanism for the cutterheads which form the tongues or grooves upon theinner edges of the two pieces of lumber.

In an application filed by me May 1, 1889, Serial No. 309,163, Ihaveshown two matcherheads arranged nearlyparallel with theline oftravel of the lumber, each of which is adapted to operateindependentlyof the other upon the inner edge of one of the pieces oflumber and have therein made claim to such arrangement. In the presentinvention I adopt the same arrangement of cutter-heads, but have deviseda simpler and more easily-adjusted mechanism for supporting thecutter-heads and have simplified the driving mechanism materially.

In the accompanying drawings, Figure 1 is a plan view of a portion ofthe frame-work of the matcher and the driving mechanism for thecutter-heads. Fig. 2 is a side elevation of the same. Figs. 3 and 4 areplan and side views, respectively, of the cutter-heads and theirsupporting and adjusting mechanism. The latter will first be described.

2 is a cutter-head, which is supported on a vertical spindle 3, runningin the boxes 4 4.

The boxes 4 4 form part of a frame 5, the side of which is planed to fitinto a groove in the bracket 6. The framework 5 is adjustable verticallyin the bracket 6 by means of the screws 7, (side Fig. 4,) which istapped into the lug 8 of the bracket 6 and is fitted by means of collars9 to thelug 10, attached to the framework 5. When its height has beenproperly adjusted, it is securely clamped in place by the screw 11. Thecutter-head 2 (side Fig. 3) is attached to the spindle 3" and issupported bya frame-work 5 which is fitted and adjusted to the bracket 6in the same manner as the frame 5. The bracket 6 is bored out, asindicated by the lines partly dotted and partly full at 12, Fig. 3, andis fitted to a pivot 13, (indicated by dotted lines in Fig. 4,)

depending from the plate 14. This plate 14 is supported by a horizontalextension 15 of the end girt 16 of the matcher-frame, being attachedthereto by bolts, as 17, or any other suitable manner. The pivot andplate 13 14 are capable of horizontal adjustment, the holes throughwhich the bolt 17 passes being slotted for that purpose and theadjusting hand wheel 13, having a screw (shown in dotted lines at 19,Fig. 3) provided .for the purpose of making this adjustment. The screwis journaled in lug 20 and tapped into lug 21, these lugs being attachedto the extension 15 and the plate 14, respectively. The adjustment justdescribed of the plate 14 and pivot 13 provides for moving bothcutterheads 3 3 to the right or left simultaneously.

To provide for adjusting their relative positions with reference to theline of travel of thelumber so as to regulate the depth of out of eachand to insure that each shall clear the edge of the piece of lumberwhich it is not operating upon, aswivelin g adjustment of the bracket 6upon the pivot 13 is provided. The bracket 6 fits closely but nottightly upon the pivot 13 and is prevented from slipping olf the pivotby thewasher 22, secured to the bottom of the pivot. (Vida Fig. 4.) Lugs23 23, one of which appears in side elevation in Fig. 4 and both ofwhich are shown in dotted lines in Fig. 3, depend from plate 14. Theyare tapped for the reception of screws 24, the ends of which abutagainst the face of the bracket 6. By screwing in one of these screwsand correspondingly backing out the other the bracket 6 will be turnedupon the pivot 13, thereby changing the positions of theheads 2 2relative to the line of travel of the lumber.

The spindles 3 3 and their attached cutterheads 2 2 are driven bypulleys 25 at their lower ends. Vt'de Figs. 1 and 2.) These pulleys 2525 are driven by quarter-twist belts 26 26 from pulleys upon thehorizontal shaft 27. As seen in the plan view, Fig. 1, the belts 26 26extend in a direction parallel to the line of travel of the lumber, sothat the pulley 25,if viewed from the driving-belts on shaft 27, isnearly hidden by the belt 25. The belt 26, which drives the pulley 25,therefore comes in contact with the belt 26, which drives the pulley 25;but this does not interfere with the proper running of the belts,because the two sides of the belts 26 26 which are in contact arerunning in the same direction and the belts, being twisted in oppositedirections, cause the spindles 3 3 to be driven in opposite directions,as indicated by the arrows. The shaft 27 may be driven from any of thedrivingshafts of the matcher.

What I claim, and desire to secure by Letters Patent, is

1. The combination, in a matcher adapted to work two pieces of lumber atthe same time, of two cutter-heads rotatable on vertical axes placedrelatively to each other in a line nearly parallel to the line of travelof the lumber and a frame-work supporting said cutter-heads androtatable as a whole upon a vertical pivot,

whereby the relative positions of the axesot' said cutter-heads to theline of travel of the lumber may be regulated.

2. The combination, in a matcher adapted to work two pieces of lumber atthe same time, of two cutter-heads rotatable on vertical axes, eachcutter-head being adapted to dress an inner edge of one piece of lumber,and a framework earrying both said cutter-heads and r0 tatable on avertical pivot, said pivot being adjustable horizontally, substantiallyas described.
